“…Due to the different ecological, climate, and zoogeographical conditions, Iran is considered a hotspot for rodents [1,2]. There are various reports of rodent parasite infectivity in various parts of Iran, while most of them have been reported zoonotic species, such as Hymenolepis nana, Hymenolepis diminuta, and Syphacia obvelata [3][4][5][6][7][8][9][10][11][12][13][14][15]. However, the rodent's parasite fauna in each ecological setting may differ due to environmental variations around the country and thus further studies in areas with different ecological settings may seem required.…”

Objectives Rodents play an important role to spread zoonotic diseases through society. The current study was carried out to collect informative data on the intestinal helminthic infections of wild rodents in Taleqan County, Alborz Province, the center of Iran, emphasizing their zoonotic aspects. Results Sixty-two killed rodents by local farmers belonging to five species were collected, among which 24 were identified as Mus musculus, 15 as Meriones persicus, 12 as Meriones libycus, 10 as Apodemus witherbyi, and 1 as Dryomys nitedula. Of them, 30 (48.4%) were infected with at least one helminth species. Rodents were infected with Hymenolepis diminuta (42%), Syphacia obvelata (21%), Hymenolepis nana (17.7%), Heligmosomoides polygyrus (9.6%), Trichuris muris (8%), and as well as a capillariid nematode that was isolated for the first time from D. nitedula in Iran. The findings of the present study revealed a significant intestinal helminthic infection of rodents in Taleqan County. Improving hygiene practices, and making a preventive attitude can be helpful to reduce the hazards of rodent-borne diseases in the area where humans, livestock, and synanthropic rodents are living close to each other.

“…In a study conducted in house mice in Taiwan, reported that 63% of them were infected with H. nana (Chou et al 1998). Other studies were also reported high prevalence, 11.42% (house mice) and 39.53% (rats) in Uttarakhand, India (Sharma et al 2013), 50% and 83% for house mice and rats respectively in Ahvaz, South-West of Iran (Rahdar et al 2017). The low prevalence of H. nana among house mice population in Kalar district might indicate that this rodent would not play critical role in the transmission of the parasite and potentially would not pose public health threat.…”

“…A larger population study in different seasons, will be recommended to confirm this. The present study has not reported infection with H. diminuta, which was different from other studies in that they reported infection with this parasite with an overall prevalence rate of 7.3%, 12.5% and 4.4%, in house mice, Rattus norvegicus and Rattus rattus, respectively in Baghdad (Hasson 2010), an overall of infection 5.71% and 44.18% in house mice and rats in Uttarakhand, India (Sharma et al 2013), 0·5% and 14·2% in house mice and black rats in Yucatan, Mexico (Panti-May et al 2017), 10% and 17% for house mice and rats respectively in Ahvaz, Iran (Rahdar et al 2017). In addition, Karim and Al-Salihi (2014) have found that 75% (3 out of 4) of the laboratory rats necropsied infected with H. diminuta.…”

Mice (Mus musculus), mammalian rodent animals belonging to the order Rodentia, family Muridae, represent one group of the most important reservoir hosts for human pathogens. In this study, a total of 127 mice were necropsied for intestinal cestode infections. Ten of them were conventionally maintained laboratory mice and the remaining 117 were house mice and collected between July 2009 and October 2016 in numerous storages of hay, rice, cereals, flour, as well as in houses from different regions of Kalar district. Six out of 10 laboratory mice were found infected with Hymenolepis nana, family Hymenolepididae, with the prevalence rate of 60%. Non-significant differences were found between both sexes. On the other hand, only one house mouse was found infected with H. nana with infection rate of 0.85%. In addition to this cestode, house mice were found infected with two unidentified cestodes from the family Cataenotaenidae, with the overall infection rate of 12.82% (15 out of 117 house mice). The overall prevalence rates of infections were 7.46% and 20% in male and female house mice; respectively. Significant differences were observed between overall prevalence of Cataenotaenidae species in infected male and female house mice. In addition, the results of this study showed that there were significant differences (P<0.01) between overall infection of laboratory and house mice regarding cestode infections. To sum up, laboratory mice were found infected with intestinal cestodes of public health concern and these might contaminate the environment, infect other animals and humans in the laboratory, and affect the accuracy of the experimental results. Therefore, an appropriate management and control of diseases in these animals, prior to the experiment, must be considered. Other cestodes were also identified belonging to the family Cataenotaenidae but it was not possible to identify them at species level due to lack of a proper morphological guide. Further study will be required to identify these parasites at species level using molecular methods. Article Info

“…Rodents are considered the most commonly occurring mammals on earth, due to their ability to adapt and thrive in almost any location and environment with the only exceptions being the Arctic and Antarctic regions. Around 4 million rodents are born every day, which lead to genetic polymorphism and hence resistance to different groups of rodenticides (Rahdar et al.,2016).…”

“…Common zoonotic diseases include: leptospirosis, rat-bite fever, Q-fever and hemorrhagic fever (Coomansingh et al., 2009). The most common endoparasites of zoonotic potential found in the brown rat are Hymenolepis , Trichinella, Moniliformis, Capillaria , Giardia , and Balantidium (Rahdar et al., 2016).…”

This study identified the endoparasites in Brown rat ( Rattus norvegicus) during May to July 2017 in Grenada, West Indies. A total of 162 rats, 76 females and 86 males were trapped from St. George and St. David parishes in Grenada. The collected fecal samples were examined for parasitic eggs and/or oocysts using simple fecal flotation technique. Adult parasites found in the intestinal tract were examined for identification. The overall prevalence of intestinal parasites among rats was 79 %. Ten helminth species were recovered, several of which were reported for the first time in rodents in Grenada. The internal parasites consist of seven nematodes ( Angiostrongylus spp., Nippostrongylus braziliensis , Heterakis spumosa , Strongyloides ratti , Aspiculuris tetraptera , Syphacia spp. and Protospirura spp.), one cestode ( Hymenolepsis diminuta ), one acanthocephalan ( Moniliformis moniliformis ) and one protozoa species ( Eimeria spp.). The most prevalent zoonotic species were Angiostrongylus spp. (35.2%), Hymenolepsis diminuta (7.4%) and Moniliformis moniliformis (3.1%). Several nonzoonotic endoparasites; which included Nippostrongylus braziliensis (50.6%), Heterakis spumosa (15.4%), Strongyloides ratti (43.2%), Aspiculuris tetraptera (2.5%), Syphacia spp . (1.9%), Protospirura spp. (1.2%) and Eimeria spp. (4.7%) were also identified. The most prevalent parasites were Nippostrongylus brasiliensis (50.6%), Strongyloides ratti (43.2%) and Angiostrongylus spp. (35.2%). Co-infections occurred with up to six species per rat showing different combinations of parasitic infections.
